Podrobnosti

Pole povolených hodnot pro parametr "action" pro normální stránky.

Tato metoda definování vlastních akcí nahrazuje zastaralý háček UnknownAction . Podrobnosti o tom, jak migrovat existující kód háčku na přístup založený na třídách, najdete v sekci migrace na stránce háčku .

Syntaxe je:

  • 'foo' => 'ClassName' - Načtěte zadanou třídu, která má podtřídy Action
  • 'foo' => true - Load the class FooAction which subclasses Action
  • 'foo' => false - The action is disabled; show an error message

Default value

Since MediaWiki 1.37, core defaults are defined in ActionFactory.php.
Verze MediaWiki:
1.37
/**
 * Array of allowed values for the "title=foo&action=<action>" parameter. See
 * ActionFactory for the syntax. Core defaults are in ActionFactory::CORE_ACTIONS,
 * anything here overrides that.
 */
$wgActions = [];
Verze MediaWiki:
1.32 – 1.36
/**
 * Array of allowed values for the "title=foo&action=<action>" parameter. Syntax is:
 *     'foo' => 'ClassName'    Load the specified class which subclasses Action
 *     'foo' => true           Load the class FooAction which subclasses Action
 *                             If something is specified in the getActionOverrides()
 *                             of the relevant Page object it will be used
 *                             instead of the default class.
 *     'foo' => false          The action is disabled; show an error message
 * Unsetting core actions will probably cause things to complain loudly.

Example

There is a lot you can do with a custom action, and the best method of discovery is to browse the Action, FormAction and FormlessAction classes in the core MediaWiki code (as these are the classes you will be extending) and to look at examples of pages that provide similar function to what you require, either in the core or in stable and well-supported extensions.

The following example covers the most common use-case, namely generating a custom page for the action, possibly with some extra URL arguments.

class ExampleAction extends Action {

	// This action is called 'example_action'.  This class will only be invoked when the specified
	// action is requested.
	public function getName() {
		// This should be the same name as used when registering the action in $wgActions.
		return 'example_action';
	}

	// This is the function that is called whenever a page is being requested using this action.
	// You should not use globals $wgOut, $wgRequest, etc.  Instead, use the methods provided
	// by the Action class (e.g. $this->getOutput()), instead.
	public function show() {
		// Create local instances of the context variables we need, to simplify later code.
		$out = $this->getOutput();
		$request = $this->getRequest();

		// The view is the same for the main page and the talk page, so if we're on the
		// talk page then we need to change $Title to point to the subject page instead.
		$title = $this->page->getTitle();
		if ( $title->isTalkPage() ) {
			$title = $title->getSubjectPage();
		}

		// Set page title.
		$out->setPageTitle( 'Example Page Title' );

		// Get some parameters from the URL.
		$param = $request->getIntOrNull( 'example_param' );

		// Do some internal stuff to generate the content (placed in $output).

		// Output the results.
		$out->addHTML( $output );
		// or
		$out->addWikiText( $output );
	}
}

Register the new action in extension.json (see extension.json schema):

	"Actions": {
		"example_action": "ExampleAction"
	},

Disable an action

To disable an action just add the following e.g. for the "raw" action to your "LocalSettings.php" file:

$wgActions['raw'] = false;
Unsetting core actions will probably cause things to complain loudly.
